BE WP-2050HL - 158 GPM (2") Water Pump w/ Honda GC Engine

Q: Hi Jim Is it okay to have the input 2 inch in and reduce the output to a 1 1/2? that would probably increase the PSI a little bit more too, right? or do I have to match both input and output with the same size hose? Thank you.

A: It is always recommended that you use the same diameter hose/piping as the suction and discharge ports on the pump. While it is sometimes necessary to reduce that diameter, it is NOT recommended that you do so by more than one size. In this case, 1-1/2" hose or piping would be the maximum reduction, While you may see an increased pressure due to the reduced piping, the pump will also see an increased backpressure on the pump. The more you reduce the hose/piping diameter, the more you increase this backpressure AND increase premature pump failure that would NOT be covered under warranty.
